1) Corrected phaseIsActive with PhaseIdx argument instead of CompIdx argument in "subtraction of dissolved gas from oil phase and vapporized oil from gas phase".
2) Fix for well accumulation calculation in case oil is absent.
Restores the original cwd after each unittest in test_basic.py. Also
simplifies add_test() in python/simulators/CMakeLists.txt such that the
Bash script wrapper run-python-tests.sh is no longer needed to run the
tests.
In OPM the matrix graph might be unsymmetric as we do not store
the full sparsity pattern for copy rows but only the diagonal.
Unfortunately, DUNE assumes that matrices from finite elements and
finite volumes have a symmetric sparsity pattern for copy rows to
and uses this assumption to create the graphs for PTScotch/ParMETIS
more easily. But PTScotch/ParMetis assume a symmetric graph.
The Polymer, Brine, and Solvent quantities would be extracted from
elements 0..#perf-1 of their pertinent container rather than from
the elements associated to the particular well.
It is only used within this context and produces a warning of the
form
ISTLSolverEbos.hpp:128:25: warning: unused variable ‘gridForConn’
unless the build configures accelerator support.
With this, a slightly more sophisticated procedure is used for well rate intialization.
Since it changes existing results, it defaults to false, giving the existing behaviour.
nvcc exits compilation if the header dune/istl/basearray.hh (form DUNE
2.6) is included as it does not seem to understand the friend declaration
there (friend class for a struct).
```
/usr/include/dune/istl/basearray.hh:101:49: error: ‘typename Dune::Imp::base_array_unmanaged<B, A>::RealIterator’ names ‘template<class B, class A> template<class T> struct Dune::Imp::base_array_unmanaged<B, A>::RealIterator’, which is not a type
friend class RealIterator<const ValueType>;

Switches between using the logarithmic and unit scaling factor based
on whether or not the well has an explicit, positive drainage radius
(WELSPECS item 7). Does presently not include the D factor.
Add a set of unit tests to exercise the facility.
